This invention relates to hose-clamps and has for its object to reduce a iinen that will rove easily ad ustable, an which will at a times assure a snug and close fitting of the members to be connected.

This invention is mainly a plicable where a hose rubber, or kind 0 a flexible tube is to be snugly an safely connected to a ri 'd outlet, or pipe. I I

QVhil the scope of application of my invention is very wide, I

invention in regard to the railroads, cars and locomotives, where hose connection is to be found between the engine and tender, and where my invention has proved very effective. A similar use for my invention will be found in re rd to automobiles and in numerous other elds.

The advantages of this invention will ap pear as the description roceeds.

With the above and ot er objects in view, the invention consists of the novel features of construction, combination and arran ments of arts, hereinafter-fully descri claim 7 and illustrated in athe accompany'ing drawings forming art of the specification, in which similar aracters of reference indicate correspondingparts in all views, and in which:

Figure 1 is a front elevation of the em-- bodiment of my invention Figure 2 is a detail sectional view of the cylindrical clam ing members taken'apart and also showing a It and ring as part of this invention; F1 3 is a similar view illustratixig a dierent form of my invention, while igure 4 illustrates another feature that may be introduced into same and is quite within the scope of this invention, and Figure-5' illustrates a bottom view of same.

The hose-clamp com rises two half cylin-. drical memberslO an 11, as shown, each member has two projections, an upper and a lower bent upon itself and indicated, these re erring to 10 by the numerals 10' and 10" and these referrmgto 11 by 11., and

11", respectively.

The lower projections 10 and 11" have a slight outward bend forming an angle of.

less than degrees with its bottom, and adapted to receive a ring or member 12.

' In placing the member 11, which as well as 10, is of a springy nature around-a hose and ipe, which are to be securel connec ,andafterward closing the c e with the upperjoints'are kept in close proximity I 11 especially point out the essential importance of my.

lacing the member.10 o posite the me'm-' r411 it'will be seenat the flat-faced, tapered projections 13, 13 of member 11 overlaps the adjoining end pieces 14, 14 60 of member 10, thereby contributing to a snug and'compact fitting of said hose and I pipe. A ring or member 12 is laced around the projections 10." and 11" t ereby clasp ing the lower joints snugly together, wh1 e 05 byapplyinga screw bolt '15, which penetrates the two 11 ward pro ections, or ears 10 and 11, and 1s ti htenecl by a hexagonal screw-nut 16. It wi be seen that to secure steadiness of movement in applying said screw-nut to said bolt it' is o importance that the screwhead 17 which is integral with the bolt, is of a square shape and placed as near the bottom of said car as possible, thereby givingstrength to said closing or tightening movement. It is evident that the- .hexagonal nut 16is placed in correspondinige 0 1y low position for a similar purpose. Wh as showing in Figure 2, the member'll has 9 two extensions or overlapping projections 13, this invention may be constructed in such 7 a manner that each half cyiindrical ring has one such projection respectively above or below as shown in Figure 3, whereby the tension in placing sai rin around a joint is mainly eliminated as t e two' semi-rings practlcallymeet on the diametrical line.

Another aspect well within the S00 e of this invention is the termination of the ower end iece' '14 into an eyelet or hook 18 fastene around the ring 12, as shown in Figure 4, to secure the presence of said ring-meln- Y her. In this instance the inwardlybent part I 19 of the hook is flatly tapered and adapted to rest against the. overlapping projection 18, tgiving further strengt to each ring- 1n While I have shown and described the preaterred embodiment of my invention, it is to be understood that many minor modifica-' tions may be resorted to within the scope of theinventio'n, and Idonot, therefore, desire to be 1' ted to the preclse'construction illustrated in the drawings.

Having thus fully described my invention, what I desire to cla1mand protect by Letters Patent is: I Y

1. A hose-clamp comprising two half-@- lindrical sections, each section rovided with two projections, bent upon t emselves for engagement with a screw-bolt inserted-
